592-HP BMW M5 30th Anniversary Model Limited to 30 Copies in U.S.

The world was introduced to the BMW M5 30 years ago, and to celebrate the milestone, BMW is building a limited run of anniversary models for 2015. Just 300 examples of the M5 30th Anniversary Edition are planned worldwide, with only 30 destined for our shores. To get one, buyers have to pay close attention to BMW's Instagram account to find out the number they need to call to reserve a car. Once they do, though, they'll have a chance at the special model, which BMW calls its most powerful ever.

Officially called the "30 Jahre M5" (German for 30 Years of the M5), the limited model's twin-turbo 4.4-liter V-8 is tuned to 600 metric hp (592 hp) and 516 lb-ft of torque. That represents an increase of 32 hp from the standard M5, and a 17-hp bump from the M5 with Competition Package. That not only makes it the most powerful M5 ever made, but also the most potent BMW production vehicle ever, according to the automaker. If you want those bragging rights, you'll have to fork over at least $138,275 (including destination) and follow BMW's Instagram feed, where the brand will reveal parts of the phone number for the reservation line between May 17 and May 21. The first 29 callers will have first dibs on purchasing a 30th Anniversary Edition M5, with the 30th car reserved for BMW of North America, which could choose to sell it at a later date.If you're one of the lucky 29 buyers, you'll be invited to a one-day M Driving School at The Thermal Club, a private motorsports park in Palm Springs, Calif. In addition to the power boost, the 30th anniversary M5 also receives an improved M Dynamic mode and M-specific Servotronic feature. A dedicated control module helps the Active M Differential to react quicker, improving traction on corner exit. BMW estimates the improvements are good for 0-60 mph acceleration of 3.7 seconds, which is likely a conservative figure considering we got 3.4 seconds out of a 2014 M5 Competition Pack.

The model comes finished in Frozen Dark Silver Metallic with black chrome "30 Jahre M5" badges adorning the kidney grilles front fenders, and rear end. A set of 20-inch bi-color M alloy wheels underpins the car, while more 30 Jahre M5 badges can be found inside along with a numbered ID plaque. The M multifunctional seats are upholstered in black Alcantara and leather, with the 30 Jahre M5 logo embroidered on the seatbacks.Check out photos of the 30th Anniversary edition M5 below, and follow BMW on Instagram at @BMWUSA if you have the means -- and the patience -- to buy the special model.
